blighted ovum

[blī′tid]
a fertilized ovum that fails to develop. On x-ray or ultrasonic visualization it appears to be a fluid-filled cyst attached to the wall of the uterus. It may be empty, or it may contain amorphous parts. Many first trimester spontaneous abortions represent the expulsion of a blighted ovum. Suction curettage may be necessary if the blighted ovum is retained.
An ovum with arrested development, which may appear as a fluid-filled sac with amorphous embryonic rests. Blighted ova are typical of grossly abnormal or anembryonic pregnancy and may occur in a background of inevitable spontaneous abortion

In a 2004 NIH pilot trial of vaginal misoprostol for anembryonic gestation and fetal/embryonic demise, a single application (repeated if necessary, after 48 hours) was successful (expulsion by 1 week, without the need for D & C) in 94% of 51 cases of embryonic/fetal demise, and in 69% of 29 anembryonic gestations.
Expulsion was most likely to be complete by day 3 among the 30 women who had had incomplete or inevitable abortion, a pattern that held on day 8, when 93% in this group had successfully expelled the products of conception, compared with 87% of the 281 women with embryonic or fetal demise and 81% of the 177 women with anembryonic gestation.
The results were less impressive for anembryonic gestation," Dr.
